Inlet Control Valve (Body) Inspection -
The valve does not require maintenance or lubrication. If air/oil
leaks develop across the valve disc during pressurized conditions (e.g., machine stopped), valve seals
should be inspected for wear and tear signs:
1. Be sure the unit is completely off and oil sump is depressurized. Disconnect, lockout and tagout
power supply to the compressor package.
2. Close (when provided) valve isolating compressor package from air system.
3. Identify (by position) each tube connected to the valve body and remove.
4. Remove four bolts (Item 13) securing valve body to compressor body and remove valve.
5. Inspect poppet seals (o-ring) (Item 6, 10) for wear and tear. Replace, if necessary.
6. Remove lock ring (Item 12) and pull out cover (Item 4).
7. Inspect seals (Items 9, 11) for wear and tear. Replace if necessary.
8. Reassemble inlet control valve in reverse order.
